Astronomers working with the Hubble Space Telescope published a curious image. It demonstrates a pair of interacting Arp-Madore 2105-332 galaxies.
Arp-Madore 2105-332 is located at a distance of 200 million light-years from Earth in the direction of the constellation Microscopium. The spectra of both galaxies show emission lines, which distinguishes them from galaxies that have characteristic discontinuities in their spectra, called absorption lines. Emission lines are generated when gases are very hot, which means they have enough energy for atoms and molecules to “excite” and emit light. Thus, they point to high-energy processes taking place inside galaxies, most likely related to the formation of new stars.
Tidal interactions have already begun to affect both galaxies. It can be noted that they are connected by a luminous bridge consisting of elongated matter and stars.
Due to the high image quality, we can also see several more galaxies that are in no way related to Arp-Madore 2105-332, which are located in such a successful way that they are lined up under the left member of the pair. In fact, the members of this “line-up” are located at a much greater distance from Earth than Arp-Madore 2105-332.
Earlier, we talked about how astronomers discovered a heterogeneity in the center of the Milky Way.
